An asymmetrical cutting tool has a partially cord-wrapped handle with a first handle panel, a second handle panel, and an intercheangeable overlay. The cutting tool further includes a folding blade, pivotably attached to the cord-wrapped/overlaid handle, and having a partially concave edge and a punch tip. The folding blade is operable to transition between a locked state and an unlocked state. Lock wear is compensated by dual eccentric thumb studs which act as a camshaft lobe to alter the position of the blade with respect to the lock while in the locked state. The partially cord-wrapped handle is configured to receive the folding blade when the blade transitions from the locked state into the unlocked state.

A knife include a handle, button, blade with an integral tang, locking mechanism within the tang, and thrust mechanism. The blade moves between closed and open positions. The button may axially slide along the handle. When the blade is in the closed position and locked, movement of the button towards the first handle end releases the locking mechanism and the thrust mechanism moves the blade to the open position. A knife includes a stop pin connected to a tang of a blade and a stop plate positioned within a knife handle. The stop plate has two angled surfaces. The stop pin mates with both angled surfaces and the blade is constrained from movement in two planes.

A folding knife is provided with a power storage device that can be charged and recharged by a charge component that wirelessly receives power from a remote source. In some embodiments, the folding knife can have a device that consumes energy such as a light, a camera, a microphone, an audio speaker, a display, etc. The power storage device and the charge component can be positioned in a scale of the handle where the substantially planar shapes of the scale, the power storage device, and the charge component are oriented in a common direction. In some embodiments, the cavities, recesses, and channels in the first scale that house these components and linking wires are strategically positioned to leave a reinforcing area that provides strength and stiffness to the handle. Various features also described improve safety of the charging system and provide connectivity with external computing systems and electronic devices.

The disclosed locking folding knife with clip actuator combines a locking mechanism with a clip mechanism. This results in a reduction of the number of required parts, simplifying the knife while maintaining functionality. The blade of the knife pivots with respect to the handle. In the preferred embodiment the blade rotates about a pin, the pin optionally surrounded by a bushing. The pin about which the knife rotates is an extension of one of the arms of the clip.

A folding knife and related method include actuating elements for locking or unlocking the blade of the knife. The actuating elements are permanently illuminated or backlit so that the actuating elements are more clearly visible in low light conditions and can therefore be safely operated. Such features for knife applications may provide advantages for particular activities where knives are commonly used, such as for law enforcement and hunting.

A folding knife can include a handle comprising a side wall having a side surface, a protrusion extending laterally from the side surface of the side wall, a blade, and a linkage assembly pivotably coupling the handle to the blade. The protrusion can have an edge extending laterally from the side surface of the side wall to the side surface of the protrusion. The edge can include a first surface portion and a second surface portion configured as a locking surface. The second surface portion can extend downwardly at an angle relative to the first surface portion. The blade can have a tang including a locking edge, and can be translatable relative to the handle between a storage position and a use position. When the blade is in the use position, the locking surface engages the locking edge to resist movement of the blade in a first direction.

A bolster-actuated folding knife may have a folding knife blade whose opening and closing is controlled by an actuator on the knife's handle. This bolster-actuator may rotate in either of two rotational directions about the same pivot as the knife blade. When a user rotates the bolster-actuator in one direction, the bolster's pin may impinge via direct contact with the knife blade forcing the knife blade fully open. When a rotates the bolster-actuator in the opposite direction bolster-actuator rotation and thus bolster pin deflection may cause the knife's locking tab to disengage from a cutout in the knife blade, unlocking the knife blade from its fully locked-open position and urging the knife blade to close. Thus, the bolster-actuated folding knife may provide a convenient means to open and close a locking, folding knife with only one hand, and without substantial interference with the knife's aesthetic appeal.

A utility knife including a handle, a blade, a first blade holder, and a spare blade holder. The spare blade holder is pivotal with respect to the handle between an open position where the recess is exposed to allow a spare blade to be removed from the spare blade holder and a closed position where the recess is within a slot of the handle to inhibit removal of the spare blade from the spare blade holder. The spare blade holder further including a cam surface and the cam surface of the spare blade holder engages a cam surface of the handle when the spare blade holder is in the closed position to urge the spare blade holder in a direction from a first longitudinal side of the handle toward a second longitudinal side of the handle to allow the first blade holder to pivot between extended and folded positions.

Embodiments of the invention are directed to a folding or butterfly knife that provides for easily changing a blade or other tool on the knife. The knife includes a first handle component; a second handle component; and a knife component. The knife component comprises a blade integrally connected to a tang, pivotally secured to the first and second handle components by an attachment section. The attachment section comprises a first plate; a second plate; an inner plate located between the first and second plates; and a kicker lever for removing and replacing the blade in the knife segment, the kicker lever comprising a protrusion and a kicker located at an upper end of the kicker lever and a lever stop located at a lower end of the kicker lever for defining the movement of the kicker lever.
